A water jet device

Abstract

A water jet device uses water-blocking ribs to disrupt the water flowing into the inner flow chamber. When the water flows through the diffusion channel, it forms a main water column and a water mist surrounding the main water column, which is then ejected and naturally drawn in through the air intake channel. When the water flow is at low pressure, the main water column and water mist collide with the diverting ribs, causing them to spray out to one side, creating a negative pressure zone on the other side. This pulls the main water column and water mist to the other side, creating a reciprocating water spray. As the water pressure gradually increases, the main water column and water mist are divided into two streams by the diverting ribs, spraying out from their respective sides with high-frequency oscillation, forming hollow, bud-like water sprays. This allows for automatic switching between different water spray patterns through water pressure. The composite water spray formed by the main water column and water mist makes it gentler and more comfortable when in contact with the skin, providing a better rinsing experience for the user.

Description

Technical Field

[0001] This invention relates to the field of jetting devices, and more particularly to a water jetting device. Background Technology

[0002] Currently, the spray function is a standard feature of smart toilets, using water flow to wash the posterior and / or feminine areas after defecation. The spray function of smart toilets is typically implemented using a spray device with a nozzle at the end of the spray bar to dispense posterior and / or feminine wash water. However, common spray devices lack a massage-like water spray, and the feminine wash water spray is too forceful, resulting in a poor user experience. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a water jet device.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A water jet device includes a body, to which a top cover is connected.

[0006] The main body is provided with an inlet, a flow chamber and an inner flow chamber in sequence along the water flow direction. At least one main water-blocking rib is provided in the flow chamber or the inner flow chamber. The top of the inner flow chamber is provided with a first water outlet that is connected to the inner flow chamber. An asymmetrical diffusion channel is provided at the outer opening of the first water outlet, so that after the water is sprayed out from the diffusion channel, a main water column and water mist surrounding the main water column are formed.

[0007] The top cover is provided with a second water outlet, and at least one diversion rib is provided inside the second water outlet. The diversion rib divides the second water outlet into a first water outlet channel and a second water outlet channel. The second water outlet is connected to the water passage of the first water outlet in the main body, and the water outlet direction of the first water outlet is towards the second water outlet. The top cover is provided with an air intake channel. One end of the air intake channel is connected to the second water outlet, and the other end of the air intake channel is connected to the atmospheric environment. The water flow sprayed from the diffusion channel is drawn in through the air intake channel.

[0008] When the incoming water flow is at low pressure, the main water column and water mist are sprayed out repeatedly between the first and second water outlet channels, forming a back-and-forth oscillating water spray; when the incoming water flow is at high pressure, the main water column and water mist are separated into two streams by the diversion ribs, and sprayed out from the first and second water outlet channels respectively, forming a hollow flower bud water spray.

[0009] Furthermore, the wall surface of the first water outlet extends upward toward the second water outlet, and the portion protruding from the orifice surface of the first water outlet forms a guide protrusion with the orifice of the first water outlet, forming a diffusion channel.

[0010] Furthermore, the angle between the placement axis of the diversion rib and the central axis of the main body is 0-90 degrees.

[0011] Furthermore, the ratio of the maximum radial dimension of the diversion rib to the radial dimension of the second outlet hole constitutes the width ratio, which ranges from 1:1.5 to 5.

[0012] Furthermore, the ratio between the distance between the bottom of the diversion rib and the water inlet end face of the second water outlet and the axial dimension of the second water outlet constitutes the first height ratio, which ranges from 1:1.2 to 6.

[0013] Furthermore, the ratio between the distance between the top of the diversion rib and the inlet face of the second outlet hole and the axial dimension of the second outlet hole constitutes the second height ratio, which ranges from 1:1 to 6.

[0014] Furthermore, the diversion ribs have an axisymmetric structure. When there is only one diversion rib, the distance between the axis of symmetry of the diversion rib and the axis of the second outlet hole does not exceed 20% of the diameter of the second outlet hole. When there is more than one diversion rib, each diversion rib is arranged at the same height in the second outlet hole.

[0015] Furthermore, the ratio of the radial dimension to the axial dimension of the second outlet hole constitutes the aperture ratio, which ranges from 1:1 to 3.3.

[0016] Furthermore, a groove is provided at the edge of the inlet end of the second water outlet, which forms an air intake channel.

[0017] Furthermore, the main body is also connected to a lower cover, which together with the main body forms a water flow cavity and an inner flow cavity, and the lower cover is provided with a secondary water-blocking rib at the position of the inner flow cavity.

[0018] The beneficial effects of this invention are:

[0019] 1. This invention provides a water jet device that uses water-blocking ribs to disrupt the water flowing into the inner flow cavity. When the water flows through the diffusion channel, it forms a main water column and water sprays containing the main water column, which are then naturally drawn in through the air intake channel. When the water flow is at low pressure, the main water column and water spray hit the diverting ribs and are sprayed to one side, creating a negative pressure zone on the other side. This pulls the main water column and water spray to the other side, creating a reciprocating water spray. As the water pressure gradually increases, the main water column and water spray are divided into two streams by the diverting ribs, sprayed from their respective sides with high-frequency oscillation, forming hollow, bud-like water sprays. This allows for automatic switching between different water sprays through water pressure. The composite water spray formed by the main water column and water spray makes it gentler and more comfortable when in contact with the skin, providing a better rinsing experience for the user.

[0020] 2. The water jet device proposed in this invention has a first water outlet portion of the wall extending upward toward the second water outlet. The portion protruding from the surface of the first water outlet orifice forms a guide protrusion with the orifice of the first water outlet. The guide protrusion forms a diffusion channel. By increasing the height difference between one side wall and the other side wall of the diffusion channel, the water flowing through the first water outlet is promoted to diffuse in a fan shape. Combined with an air intake channel connected to the outside air, the water jetted from the diffusion channel forms a main water column in the middle, surrounded by water droplets of water mist. The water is fully mixed with air, making the water smoother and improving the user experience.

[0021] 3. The water jet device proposed in this invention has an angle of 0-90 degrees between the placement axis of the diversion ribs and the central axis of the main body. Experiments have shown that the direction of water splashing is perpendicular to the placement axis of the diversion ribs. Therefore, diversion ribs with different angles can be designed according to actual needs to achieve water splashing in different directions.

[0022] 4. The water jet device proposed in this invention comprises a width ratio, a first height ratio, and a second height ratio, respectively, formed by the size of the diverting rib, the arrangement position of the diverting rib in the second water outlet hole, and the ratio between the size of the diverting rib and the second water outlet hole. The shape of the water spray is controlled by adjusting the ratio of the width ratio, the first height ratio, and the second height ratio.

[0023] 5. The water jet device proposed in this invention has a symmetrical structure for the diversion ribs, which makes it possible to obtain a more stable water spray shape.

[0024] 6. The water jet device proposed in this invention has a second water outlet with a diameter ratio consisting of the ratio of its radial dimension to its axial dimension. The shape of the water jet is adjusted by controlling the diameter ratio.

[0025] 7. The water jet device proposed in this invention has an air intake channel at the edge of the inlet end of the second water outlet. The air intake channel located at the inlet end helps to form a better air intake effect. The greater the air intake, the better the stability of the water spray pattern through the second water outlet, and the less obvious the bifurcation phenomenon formed by the water spray confluence.

[0026] 8. The water jetting device proposed in this invention has a lower cover connected to the main body. The lower cover is provided with a secondary water-blocking rib at the position of the inner flow cavity. The secondary water-blocking rib and the main water-blocking rib work together to enhance the disturbance effect of the water flow. Attached Figure Description

Detailed Implementation

[0042] The following is combined with Figure 1-13 The present invention will be described in detail below.

[0043] A water jetting device includes a body 10 connected to a top cover 20. The body 10 has an inlet, a flow chamber 101, and an inner flow chamber 102 arranged sequentially along the water flow direction. The water outlet direction of the flow chamber 101 is tangential to the inner flow chamber 102. At least one main water-blocking rib 401 is provided within the flow chamber 101 or the inner flow chamber 102. A first water outlet 601 communicating with the top of the inner flow chamber 102 is provided. An asymmetrical diffusion channel is provided at the outer opening of the first water outlet 601, so that after the water is ejected from the diffusion channel, a main water column and surrounding water jets are formed. The main water column produces water mist; the upper cover 20 is provided with a second water outlet 602, and at least one diversion rib 50 is provided inside the second water outlet 602, the diversion rib 50 at least divides the second water outlet 602 into a first water outlet channel 6021 and a second water outlet channel 6022; the second water outlet 602 is connected to the water path of the first water outlet 601, and the water outlet direction of the first water outlet 601 is towards the second water outlet 602; the upper cover 20 is provided with an air intake channel 70, one end of the air intake channel 70 is connected to the second water outlet 602, and the other end of the air intake channel 70 is connected to the atmospheric environment.

[0044] Therefore, this invention disrupts the water flowing into the inner flow cavity 102 through the main water-blocking rib 401. When the water flows through the diffusion channel, it forms a main water column and water droplets enveloping the main water column, which are then ejected and naturally aspirated through the air intake channel 70. When the water flow is at low pressure, after the main water column hits the diversion rib 50, the main water column and water droplets are ejected from the first water outlet channel 6021. Figure 12 As shown in (a). At this time, a negative pressure zone is formed in the second water outlet channel 6022, thereby pulling the main water column away from the first water outlet channel 6021 to the second water outlet channel 6022, as shown in (a). Figure 12 As shown in (b), this cycle repeats, creating a water column that can oscillate back and forth. As the water pressure gradually increases, the main water column and water mist are divided into two streams by the diversion ribs 50, which are ejected from the first water outlet channel 6021 and the second water outlet channel 6022 respectively, accompanied by high-frequency oscillation, causing the water droplets to form hollow, bud-like water droplets, as... Figure 13As shown, the system automatically switches between different water spray patterns by adjusting the water pressure. The composite water spray pattern, consisting of the main water jet and water mist, makes the water feel gentler and more comfortable when it comes into contact with the skin, providing users with a better rinsing experience.

[0045] In this embodiment, the main water-blocking ribs 401 can be disposed on the side wall of the water flow cavity 101 or inside the water flow cavity 101. The larger the cross-section and the greater the number of main water-blocking ribs 401, the better the turbulence effect on the incoming water flow, resulting in a more concentrated main water jet ejected from the second outlet. Specifically, in this embodiment, the main water-blocking ribs 401 are disposed at the 6 o'clock position on the side wall of the water flow cavity 101, such as... Figure 9 As shown.

[0046] In this embodiment, a portion of the wall surface of the first water outlet 601 extends upward toward the second water outlet 602. The portion protruding from the orifice surface of the first water outlet 601 forms a guide protrusion 103 with the orifice of the first water outlet 601, and the guide protrusion 103 forms a diffusion channel. Specifically, the guide protrusion 103 is a semi-annular protrusion, and another portion of the wall surface of the first water outlet 601 is recessed downward away from the second water outlet 602, thereby increasing the height difference between one side wall surface and the other side wall surface of the diffusion channel, promoting the water flowing through the first water outlet 601 to diffuse in a fan shape. Combined with the air intake channel 70 connected to the outside air, the water sprayed from the diffusion channel forms a main water column in the middle, surrounded by water mist. The water is fully mixed with air, making the water softer and improving the user experience.

[0047] Experiments have shown that the direction of water splash oscillation is perpendicular to the placement axis 501 of the diversion rib 50. Therefore, diversion ribs 50 with different angles can be designed according to actual needs to achieve water splash oscillation in different directions. Thus, the angle ∠1 between the placement axis 501 of the diversion rib 50 and the central axis 104 of the body 10 ranges from 0 to 90 degrees. Specifically, in this embodiment, ∠1 is 90 degrees. Figure 8 As shown, when the water flow is under low pressure, the water splash effect is a back-and-forth swing.

[0048] In this embodiment, the ratio of the maximum radial dimension D1 of the diverting rib 50 to the radial dimension D of the second water outlet 602 constitutes the width ratio, which ranges from 1:1.5 to 5. A larger width ratio D1 / D results in a more pronounced water flow oscillation effect under low pressure and a smaller bud-like water flow under high pressure; conversely, a smaller width ratio D1 / D results in a less pronounced water flow oscillation effect under low pressure and a larger bud-like water flow under high pressure. Specifically, when the water flow rate is greater than 350 mL / min, the water flow is considered high pressure; conversely, when it is less than 350 mL / min, the water flow is considered low pressure. The low-pressure water flow rate range is 200-350 mL / min, and the high-pressure water flow rate range is 350-600 mL / min.

[0049] In this embodiment, the ratio of the distance H1 between the bottom of the diversion rib 50 and the water inlet end face of the second water outlet 602 to the axial dimension H of the second water outlet 602 constitutes a first height ratio, with the range of the first height ratio H1 / H being 1:1.2-6. Furthermore, the ratio of the distance H2 between the top of the diversion rib 50 and the water inlet end face of the second water outlet 602 to the axial dimension H of the second water outlet 602 constitutes a second height ratio, with the range of the second height ratio H2 / H being 1:1-6. The larger the values ​​of the first height ratio H1 / H and the second height ratio H2 / H, the more pronounced the water flow's splashing effect under low pressure, and the smaller the bud-like splashes formed under high pressure. Conversely, the smaller the values ​​of the first height ratio H1 / H and the second height ratio H2 / H, the less pronounced the water flow's splashing effect under low pressure, and the larger the bud-like splashes formed under high pressure. Therefore, the larger the values ​​of the first height ratio H1 / H and the second height ratio H2 / H, the higher the diversion ribs 50 are arranged within the second outlet hole 602, such as... Figure 7 (a) Figure 7 (b) and Figure 7 (c) The diagram shows the states of the diversion rib 50 when it is located in the middle, top, and bottom of the second water outlet 602. Specifically, in this embodiment, the diversion rib 50 is located in the lower middle position of the second water outlet 602.

[0050] In this embodiment, the diversion ribs 50 have an axisymmetric structure. When there is only one diversion rib 50, the distance between the axis of symmetry of the diversion rib 50 and the axis of the second water outlet 602 does not exceed 20% of the diameter of the second water outlet 602. When there is more than one diversion rib 50, all diversion ribs 50 are arranged at the same height within the second water outlet 602. Figure 6As shown. Furthermore, the more diversion ribs 50 there are, the better the blocking effect on the water and the better the diversion effect. However, at the same time, the water jet velocity is reduced to a greater extent, and the shape of the water droplets exiting the second water outlet 602 is worse. Therefore, the number of diversion ribs 50 is generally at most two. Specifically, in this embodiment, the number of diversion ribs 50 is one, and the axis of symmetry of the diversion rib 50 coincides with the axis of the second water outlet 602.

[0051] In this embodiment, the shape of the diversion rib 50 includes various styles, including but not limited to such as Figure 10 (a) shows an inverted teardrop shape, as... Figure 10 (b) shows an upright teardrop shape, as Figure 10 (c) shows a cylindrical or semi-cylindrical shape, such as Figure 10 (d) shows the square schematic diagram and as shown in the figure. Figure 10 As shown in (e), the elliptical shape and the diversion ribs 50 of the above-mentioned style can also achieve the desired water splash effect.

[0052] In this embodiment, the ratio of the radial dimension D to the axial dimension H of the second water outlet 602 constitutes the aperture ratio. The aperture ratio D / H ranges from 1:1 to 3.3. The larger the aperture ratio D / H is, the larger the resulting bud-like water splash is, and vice versa.

[0053] In this embodiment, a groove is provided at the edge of the inlet end of the second water outlet 602, forming an air intake channel 70. The air intake channel 70 located at the water inlet end helps to form a better air intake effect. The greater the air intake, the better the stability of the water spray pattern through the second water outlet 602, and the less obvious the bifurcation phenomenon formed by the water spray confluence.

[0054] In this embodiment, the shape of the second water outlet 602 includes various styles, including but not limited to circular, elliptical, square, and rhomboid shapes. Under high-pressure water flow conditions, when the second water outlet 602 is circular, such as... Figure 11 As shown in (a), the water droplets are hollow, bud-like droplets; when the second water outlet 602 is square, as... Figure 11 As shown in (b), Figure 11 As shown in (a), the water droplets are hollow, sheet-like; when the second water outlet 602 is rhomboid, as... Figure 11 As shown in (c), the water splash is a hollow rhomboid shape.

[0055] In this embodiment, the main body 10 is also connected to a lower cover 30. The lower cover 30 and the main body 10 together form a water flow cavity 101 and an inner flow cavity 102. The lower cover 30 is provided with a secondary water-blocking rib 402 at the position of the inner flow cavity 102. The secondary water-blocking rib 402 and the main water-blocking rib 401 work together to enhance the disturbance effect of the water flow, making the main water column sprayed from the second outlet more concentrated.

[0056] The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand and implement the present invention. They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
